Expansion Joint: Single unrestrained

This is the simplest and the most used type of Expansion Joint and consist of a single bellows and ends connections. This Expansion Joint will deflect in any mode of bellows deflection. This type of Expansion Joint will require the most control of the adjacent piping respecting to the guides and anchors. The guides and anchors will be the appropriates to control the pipe expansion according to the Expansion Joint specified values because this type will not resist any force other than the spring force of the bellows so the main anchors and the directional main anchors will be designed to withstand the forces and moments imposed upon them.
